Definitions
- the invention described here relates to a cabinet for electrical equipment, implemented in a particularly light and stiff construction.
- Electrical equipment cabinets are usually made with a framework of steel, covered by walls of sheet metal, of which a part are openable cabinet doors. If there is added the requirement that the cabinet shall withstand large mechanical stresses, inter alia vibrations during an earthquake, the cabinet will be heavy, especially if it is large, with a height of about 2 m. If there is still further a requirement that the cabinet shall be transported with associated electric equipment in place, the cabinet must be made even stronger and heavier. This means that all the requirements made on the cabinet will be so contradictory that they cannot be met.
- the object of the present invention is to provide a cabinet for electrical equipment, implemented such that it is sufficiently light to be transported with associated electrical equipment in place, while being at the same time so stiff that it meets the requirements of resistance to specified mechanical stresses.
- the cabinet is characterized as disclosed in the characterizing portions of the following claims.
- Figure 2 illustrates one end wall of the cabinet and Figure 3 is a cross section of the end wall.
- the exemplifying cabinet in accordance with the invention is fabricated with a flat frame part 1 as its bottom, with a similar frame part 2 as its top. Upstanding fastening cleats 3 are welded to each short side of both frame parts 1, 2 at right angles to the plane of the respective part. Two box-section end walls 4, which are open at bottom and top, are placed over, and removably fastened to the cleats 3.
- the cleats 3 are made from steel sheet pressed into a corrugated configuration and are welded to the frame parts 1, 2 with a weld 5. In the case illustrated here there are 6 captive nuts attached to each cleat 3. In alternative cabinet embodiments a different number of captive nuts is used.
- Both box-secton end walls 4 are made up from an interior steel sheet 7 and an exterior steel sheet B, which are welded together along the long sides of the wall. After being placed over the fastening cleats 3, the end walls 4 are screwed to them through both the interior sheet and the exterior sheet using the captive nuts attached to the cleats.
- a locating angle cleat 9 is welded to each of the short sides of the frame part and is directed in the same direction as the cleats 3.
- the angle cleats 9 are disposed such as to bear against one narrow side of the end wall 4 to locate the end wall on the respective parts 1 and 2.
- the locating cleat 9 is also provided with a captive nut for a screw passing through the interior sheet 7 of the end wall.
- the long sides of the box-section end walls are formed as flanges 11, 12, and to these there are fastened corner posts supporting cabinet doors etc as required.
- the corner posts and the cabinet doors are not shown on the drawing since they do not constitute any part of the invention.
- the weld 5 is run along the cleat 3 so that it does not interfere with the end wall 4 bearing against the frame part 1, 2.
- its height is 2,100mm, width 1,200 mm and depth 400 mm.
- the cleats 3 are made from 2,5 mm thick steel sheet and the end wall 4 is made from steel sheet with a thickness of 1 mm on the inside and 1,5 mm on the outside. Other dimensions are applicable to alternative forms of cabinet.
- Cabinets in accordance with the invention are sufficiently light to enable their being transported with all their associated electrical equipment in place, and sufficiently strong to withstand specified mechanical stresses, inter alia vibrations caused by earthquakes.

Abstract
Une armoire, pour des équipements électriques par exemple, présente une structure particulièrement légère et rigide. L'armoire comprend une partie cadre plate comme fond (1) et une partie supérieure cadre (2) de même type, des languettes verticales de fixation (3) étant rigidement attachées aux côtés courts des parties de cadre, en angle droit avec le plan de celles-ci. Deux parois terminales (4) à section caisson ouvertes en haut et en bas sont placées sur les languettes de fixation (3) et attachées de façon amovible à celles-ci. La feuille de matériau dont sont composées les languettes de fixation (3) est ondulée, et ses ondulations sont perpendiculaires au plan des parties de cadre (1, 2) de façon à s'appuyer contre la feuille intérieure et la feuille extérieure des parois terminales.A cabinet, for electrical equipment for example, has a particularly light and rigid structure. The cabinet comprises a flat frame part as the bottom (1) and an upper frame part (2) of the same type, vertical fixing tabs (3) being rigidly attached to the short sides of the frame parts, at right angles to the plane. of these. Two end walls (4) with box section open at the top and bottom are placed on the fixing tabs (3) and removably attached to them. The sheet of material from which the fixing tabs (3) are made up is corrugated, and its corrugations are perpendicular to the plane of the frame parts (1, 2) so as to bear against the inner sheet and the outer sheet of the end walls .
